I have been active on 1.3 GHz EME
from two different systems, a 5 meter homemade
dish and an 8 M homemade dish. I was only active
on 1.3 GHz, but the 8M dish was also used as a
ground station to help the students from
Aalborg
University make contact with their satellite
! In 2000, I designed
and build a 8 meter dish for EME use. The dish
was operational until 2003, were I kind of lost
interest in the Ham Radio hobby (still have my
call sign though, you never know :o)
The 8 meter dish (and the
observatory)
The tower that supported the
dish. rotated around a solid steel post, 100 mm
in diameter, 150 cm high. The tower turned 300
degrees on wheels that drove on a 2 meter (in
diameter) solid bar, made of 30 x 50 mm
steel. Azimuth drive was electrical, Elevation
was hydraulic.
The following pictures shows
some of the steps during the building process of
the dish
Construction of the dish:
Pouring concrete for the
dish, preparing, and finally the dish is up !
 
Mounting of hydraulics, motors
and feed system:
The first dish, a 5 meter
dish, was operational from 1993, and was sold to
Hans, OZ6OL, in 1998 where my construction of
the 8 x 15 element VHF array began. Hans later
also bought my big 8 meter dish in 2003.
